Does anyone have any information about Ardnagasson, Ireland or any suggestions on where I can find some info? I have a passenger list for a trip from Londonderry, Ireland to Boston, MA in May 1894 which lists Ardnagasson as the last residence of Isabella Ray Patterson and her three sons, all four of whom were visiting from America. This town is also listed as the last residence for Isabella's sister Ellen Ray, though I'm not sure if she'd been to America before or not.

I thought this must have been the town they were visiting and was hoping it would lead me to more of Isabella and Ellen's family, but in searching for Ardnagasson I haven't been able to find anything. All I get is a couple of unrelated Ellis Island entries, which have the town name spelt the same so I don't think it's just misspelt in my record.

Thanks for any help you can give!
